Materials Needed:
- 3 number generators (dice)
- graph paper
What To Do?
- Make a prediction about which sum of two number generators will appear the most times when you roll the dice.
- Each person in the group should collect the information generated from this activity. Decide as a group if each person will take a turn rolling the dice or if one person will roll for the entire group.
- Roll dice the 50 times and record the sum of the dice each time the diceis rolled.
- Each person should display the information you have collected in the form of a histogram using grid paper. The following link will give you an idea how to set up your histogram.
- Discuss the results with your group.
- Answer the following questions.
- Repeat this activity using 3 dice.
Questions
- How did your results compare to your prediction?
- Did you find you find any patterns between the 2 dice and 3 dice activities?
- How does your data compare with others that have collected the same data?
- Can you make any conclusions about the probability of rolling dice?
